Smallest Blink Sketch Ever?

This is just a fun video to show a small blink sketch. The sketch is run on the Parallax Propeller P1 running Tachyon Forth.

Thank you! Happy Holidays. All the best to you and your family in 2024.

Thank You .. Happy New Year.

The blink example is from "Getting Started with Arduino" Massimo Banzi 2nd edition 😃, I don't know what is worse, that I'm watching this over the holidays or that I actually recognized the page! Thanks for videos 😊.

[@0033mer]

Yes ... you are correct. You would make a good detective.

[@jackwody7774]

Even simpler is to complement the LED state, call the delay, then loop

[@Edmorbus]

Thanks for sharing and happy new year

[@0033mer]

You're welcome. Happy new year to you.

[@markgreco1962]

You were right that was interesting

[@johncatsoulis]

Great video Ken, but I have to say... "Easier with a Scamp!" ;) Happy new year.

[@0033mer]

Yes, I was thinking that if "Blink" would continue to blink. Happy New Year John. Just watched the news. I see you have had some storm activity in your area.

[@GoatZilla]

suspect there's a way to make the sketch smaller...

[@Cyklonus]

👍👍

I thought this was going to get into bare metal programming with machine language. Your parallax code is still a huge program, you just don't see it because it's behind a bunch of classes and libraries.

[@0033mer]

At the beginning of the video and in the description I indicated it was just a "fun" video. Most of the viewers caught on and ran with it giving their funny solutions. The purpose of the video was to show beginners how they could type a few simple commands to get an instant response from a microcontroller. I have done other videos using assembler and the response was " nobody does assembler anymore" so as a content creator you lose either way.

Smallest is to use 555 timer. No code needed ;-)

[@p_mouse8676]

Definitely not smallest.
Smaller is one Schmitt inverter and it can even be done with just two transistors or even a single one with a bit of trickery😉👍😎

[@pileofstuff]

My favourite coding language: solder

[@0033mer]

Use a blinking LED. No 555 needed. :o)

[@paulthomas4917]

the smallest, one relay one cap.

[@goodgamer339]

But even if we are talking about a real sketch this isn't the smallest one possible. You can reduce the compiled program size massively by switching the pins directly, not using the libraries for delays or anything and deleting the loop and setup and just using your own main. So even in the realm of blinking an led via code this is still not the smallest sketch.

Elon Musk could make it smaller if he wanted to 😤
